DEAR PURE SILVERS,
For decades, when printing with variable contrast (aka multigrade) papers I have used Wratten 0C (amber/orange) safelights with 15 watt bulbs no less than 6 feet away from my paper. I regularly do fog tests and have never discovered any fog for up to 15 minutes under the safelights.
I was just checking the Bergger site and they recommend 1A (red) filters for their VC/MG papers. What planet have I been living on? Did I 
miss something these last 30 years?

                                   CHEERS!

                                               BOB
I don't know why Bergger recommends the 1A, perhaps their papers are sensitized further into the green/yellow region that most VC paper. The 1A is safe for any VC paper (or graded paper) but most people find a red safelight less comfortable to work under than the OC. Have you made a fogging test of the Bergger paper using the OC filter? I don't think there is any reason to switch to a red filter for papers that recommend the OC or Ilford equivalent.
